This documentation is for Mistral AI SDK v1. You can find more details on how to migrate from v0 to v1 here
Before you begin, you will need a Mistral AI API key.
- Get your own Mistral API Key: https://docs.mistral.ai/#api-access
- Set your Mistral API Key as an environment variable. You only need to do this once.
# set Mistral API Key (using zsh for example)
$ echo 'export MISTRAL_API_KEY=[your_key_here]' >> ~/.zshenv
# reload the environment (or just quit and open a new terminal)
$ source ~/.zshenvPIP
pip install mistralaiPoetry
poetry add mistralaiThis example shows how to create chat completions.
# Synchronous Example
from mistralai import Mistral
import os
s = Mistral(
api_key=os.getenv("MISTRAL_API_KEY", ""),
)
res = s.chat.complete(model="mistral-small-latest", messages=[

asyncio.run(main())You can run the examples in the examples/ directory using poetry run or by entering the virtual environment using poetry shell.
Prerequisites
Before you begin, ensure you have AZUREAI_ENDPOINT and an AZURE_API_KEY. To obtain these, you will need to deploy Mistral on Azure AI.
See instructions for deploying Mistral on Azure AI here.
Here's a basic example to get you started. You can also run the example in the examples directory.
import asyncio
import os
from mistralai_azure import MistralAzure
client = MistralAzure(
azure_api_key=os.getenv("AZURE_API_KEY", ""),
azure_endpoint=os.getenv("AZURE_ENDPOINT", "")
)
async def main() -> None:
res = await client.chat.complete_async(
max_tokens= 100,
temperature= 0.5,
messages= [
{
"content": "Hello there!",
"role": "user"
}
]
)
print(res)
asyncio.run(main())The documentation for the Azure SDK is available here.
Prerequisites
Before you begin, you will need to create a Google Cloud project and enable the Mistral API. To do this, follow the instructions here.
To run this locally you will also need to ensure you are authenticated with Google Cloud. You can do this by running
gcloud auth application-default loginStep 1: Install
Install the extras dependencies specific to Google Cloud:
pip install mistralai[gcp]Step 2: Example Usage
Here's a basic example to get you started.
import asyncio
from mistralai_gcp import MistralGoogleCloud
client = MistralGoogleCloud()
async def main() -> None:
res = await client.chat.complete_async(
model= "mistral-small-2402",
messages= [
{
"content": "Hello there!",
"role": "user"
}
]
)
print(res)
asyncio.run(main())The documentation for the GCP SDK is available here.

Server-sent events are used to stream content from certain
operations. These operations will expose the stream as Generator that
can be consumed using a simple for loop. The loop will
terminate when the server no longer has any events to send and closes the
underlying connection.
from mistralai import Mistral
import os
s = Mistral(
api_key=os.getenv("MISTRAL_API_KEY", ""),
)
res = s.chat.stream(model="mistral-small-latest", messages=[
{
"content": "Who is the best French painter? Answer in one short sentence.",
"role": "user",
},
])
if res is not None:
for event in res:
# handle event
print(event, flush=True)Certain SDK methods accept file objects as part of a request body or multi-part request. It is possible and typically recommended to upload files as a stream rather than reading the entire contents into memory. This avoids excessive memory consumption and potentially crashing with out-of-memory errors when working with very large files. The following example demonstrates how to attach a file stream to a request.
Tip
For endpoints that handle file uploads bytes arrays can also be used. However, using streams is recommended for large files.
from mistralai import Mistral
import os
s = Mistral(
api_key=os.getenv("MISTRAL_API_KEY", ""),
)
res = s.files.upload(file={
"file_name": "your_file_here",
"content": open("<file_path>", "rb"),
})
if res is not None:
# handle response
passSome of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.
To change the default retry strategy for a single API call, simply provide a RetryConfig object to the call:
from mistral.utils import BackoffStrategy, RetryConfig
from mistralai import Mistral
import os
s = Mistral(
api_key=os.getenv("MISTRAL_API_KEY", ""),
)
res = s.models.list(,
RetryConfig("backoff", BackoffStrategy(1, 50, 1.1, 100), False))
if res is not None:
# handle response
passIf you'd like to override the default retry strategy for all operations that support retries, you can use the retry_config optional parameter when initializing the SDK:
from mistral.utils import BackoffStrategy, RetryConfig
from mistralai import Mistral
import os
s = Mistral(
retry_config=RetryConfig("backoff", BackoffStrategy(1, 50, 1.1, 100), False),
api_key=os.getenv("MISTRAL_API_KEY", ""),
)
res = s.models.list()
if res is not None:
# handle response
passHandling errors in this SDK should largely match your expectations. All operations return a response object or raise an error. If Error objects are specified in your OpenAPI Spec, the SDK will raise the appropriate Error type.
| Error Object | Status Code | Content Type |
|---|---|---|
| models.HTTPValidationError | 422 | application/json |
| models.SDKError | 4xx-5xx | / |
from mistralai import Mistral, models
import os
s = Mistral(
api_key=os.getenv("MISTRAL_API_KEY", ""),
)
res = None
try:
res = s.models.list()
except models.HTTPValidationError as e:
# handle exception
raise(e)
except models.SDKError as e:
# handle exception
raise(e)
if res is not None:
# handle response
passYou can override the default server globally by passing a server name to the server: str optional parameter when initializing the SDK client instance. The selected server will then be used as the default on the operations that use it. This table lists the names associated with the available servers:
| Name | Server | Variables |
|---|---|---|
prod |
https://api.mistral.ai |
None |
from mistralai import Mistral
import os
s = Mistral(
server="prod",
api_key=os.getenv("MISTRAL_API_KEY", ""),
)
res = s.models.list()
if res is not None:
# handle response
passThe default server can also be overridden globally by passing a URL to the server_url: str optional parameter when initializing the SDK client instance. For example:
from mistralai import Mistral
import os
s = Mistral(
server_url="https://api.mistral.ai",
api_key=os.getenv("MISTRAL_API_KEY", ""),
)
res = s.models.list()
if res is not None:
# handle response
passThe Python SDK makes API calls using the httpx HTTP library. In order to provide a convenient way to configure timeouts, cookies, proxies, custom headers, and other low-level configuration, you can initialize the SDK client with your own HTTP client instance.
Depending on whether you are using the sync or async version of the SDK, you can pass an instance of HttpClient or AsyncHttpClient respectively, which are Protocol's ensuring that the client has the necessary methods to make API calls.
This allows you to wrap the client with your own custom logic, such as adding custom headers, logging, or error handling, or you can just pass an instance of httpx.Client or httpx.AsyncClient directly.
For example, you could specify a header for every request that this sdk makes as follows:
from mistralai import Mistral
import httpx
http_client = httpx.Client(headers={"x-custom-header": "someValue"})
s = Mistral(client=http_client)or you could wrap the client with your own custom logic:
from mistralai import Mistral
from mistralai.httpclient import AsyncHttpClient
import httpx
class CustomClient(AsyncHttpClient):
client: AsyncHttpClient
def __init__(self, client: AsyncHttpClient):
self.client = client
async def send(
self,
request: httpx.Request,
*,
stream: bool = False,
auth: Union[
httpx._types.AuthTypes, httpx._client.UseClientDefault, None
] = httpx.USE_CLIENT_DEFAULT,
follow_redirects: Union[
bool, httpx._client.UseClientDefault
] = httpx.USE_CLIENT_DEFAULT,
) -> httpx.Response:
request.headers["Client-Level-Header"] = "added by client"
return await self.client.send(
request, stream=stream, auth=auth, follow_redirects=follow_redirects
)
def build_request(
self,
method: str,
url: httpx._types.URLTypes,
*,
content: Optional[httpx._types.RequestContent] = None,
data: Optional[httpx._types.RequestData] = None,
files: Optional[httpx._types.RequestFiles] = None,
json: Optional[Any] = None,
params: Optional[httpx._types.QueryParamTypes] = None,
headers: Optional[httpx._types.HeaderTypes] = None,
cookies: Optional[httpx._types.CookieTypes] = None,
timeout: Union[
httpx._types.TimeoutTypes, httpx._client.UseClientDefault
] = httpx.USE_CLIENT_DEFAULT,
extensions: Optional[httpx._types.RequestExtensions] = None,
) -> httpx.Request:
return self.client.build_request(
method,
url,
content=content,
data=data,
files=files,
json=json,
params=params,
headers=headers,
cookies=cookies,
timeout=timeout,
extensions=extensions,
)
s = Mistral(async_client=CustomClient(httpx.AsyncClient()))This SDK supports the following security scheme globally:
| Name | Type | Scheme | Environment Variable |
|---|---|---|---|
api_key |
http | HTTP Bearer | MISTRAL_API_KEY |
To authenticate with the API the api_key parameter must be set when initializing the SDK client instance. For example:
from mistralai import Mistral
import os
s = Mistral(
api_key=os.getenv("MISTRAL_API_KEY", ""),
)
res = s.models.list()
if res is not None:
# handle response
passTo emit debug logs for SDK requests and responses you can pass a logger object directly into your SDK object.
from mistralai import Mistral
import logging
logging.basicConfig(level=logging.DEBUG)
s = Mistral(debug_logger=logging.getLogger("mistralai"))Generally, the SDK will work well with most IDEs out of the box. However, when using PyCharm, you can enjoy much better integration with Pydantic by installing an additional plugin.
While we value open-source contributions to this SDK, this library is generated programmatically. Any manual changes added to internal files will be overwritten on the next generation. We look forward to hearing your feedback. Feel free to open a PR or an issue with a proof of concept and we'll do our best to include it in a future release.
